a. Marigold with no fertilizer
b. Type of fertilizer
c. Plant growth
d. Amount of water
Answers
Answer:
a. Marigold with no fertilizer
Explanation:
An experiment contains variables including independent and dependent variables. The independent variable is the variable that is changed by the experimenter, which is the TYPE OF FERTILIZER in this case, while the dependent variable is the measured variable, which is the GROWTH OF MARIGOLDS in this experiment.
However, a control group is a group that does not receive any experimental treatment. In other words, the independent variable is unchanged in the control group. The control group is regarded as the "normal" used to compare with the experimental group (group that receives treatment). In this experiment, the group of marigolds that DOES NOT RECEIVE FERTILIZER is the control group.
The affected variable in an experiment is the

If by "I" you mean Independant, then no; The Dependent variable will the one that changes.
What are two abiotic and two biotic conditions in a coral reef that provide the conditions necessary for it to have high biodiversity? How could a disturbance affect the biodiversity of the coral reef?
Answers
Answer:
The two abiotic conditions in the coral reef that contribute to the high biodiversity are:
TemperatureSunlightWhilst the abiotic factors are
Plant and BacteriaExplanation:
The coral reef which covers a space of 115,831 square miles (or 30 million hectares os space) is home to a rich diversity of aquatic life (plants and animals alike). Being the largest coral reef on earth a lot of attention is given to it to ensure that its health and functionality is preserved.
The above factors contribute immensely to the stability and operability of the great reef.
The coral reef abounds with many aquatic animals such as crabs, herbivorous fish, sea turtles, sea urchins etc Many of these feed off microscopic plants such as the phytoplankton (that is tiny plants) and microscopic animals referred to as zooplankton. The zooplankton in turn feed off microscopic plant, bacterioplankton and even other zooplankton.
It is easy to see that at the base of the food chain lies Phytoplankton and bacterioplankton. This group require sunlight to thrive.
The smaller herbivorous fish, crabs, sea turtles and urchins on the other hand, constitute food for larger animals such as sharks, Baracuda etc.
It is also important to note that these microscopic life (plant and animals) require a certain temperature to thrive. If the water body in these eco system were to exceed a certain temperature, it is highly doubtful that they would survive. The death the the plant and animal life at the base of the food chain will completely disrupt the entire biodiversity and may even lead to its extinction.

Defined as variation of life on Earth, ____________ is the number and relative abundance of different species.
Answers
Answer: Diversity
Explanation: The earth is composed of different species of organisms spread across various parts and regions of the earth. The idea of having varying classes of species scattered on the earth is called diversity culled from the word diverse, which is used to describe a property of Variation in component. Hence, diversity explains the variation in the number and size of different species, culture and languages (biodiversity) and other components of the human existence. Additionally, the concept of diversity helps us realize the need to respect and embrace our differences in other to foster progressive relationship.

All autotrophs produce valuable organic molecules. What makes these organic molecules so valuable to living organisms
Answers
Answer:
The valuable organic molecules produced by autotrophs serve as sources of food for the heterotroph and supply the necessary nutrients living organisms need to grow and survive.
Without these valuable organic molecules living organisms can not survive , grow and develop.
The organic molecules serve as sources of energy needed to fuel biological processes in the organisms.
Explanation:
Autotrophs are group of organisms that can produce their own food through the process of photosynthesis where inorganic molecules are converted to organic molecules i.e they use light energy from the sun with water and carbondioxide to produce carbohydrates and oxygen.
Heterotrophs or other living organisms depend on autotrophs for the supply of organic matter as food nutrients and sources of energy needed for cellular or biologic processes.

Did the enzymes from Claire's small intestine break down the
protein at a low, normal or high rate?
Answers
Answer: low rate
Explanation:
Claire is a Great Dane who was losing weight despite the fact that she is eating. Claire doesn't have an increase in appetite and also doesn't have enough energy that is required for her to play.
Claire is losing weight because food the enzymes in her body doesn't break down the food that she eats. When compared to a dog that was healthy, the enzymes from Claire's small intestine broke down protein at a low rate.
Small intestine of Claire break down the protein at a low rate.
The enzymes from Claire's small intestine break down the protein at a low rate because the proteases is present in a very low amount in the small intestine. The proteases enzyme is responsible for the break down of proteins.
If proteases is present in large amount then the protein present in food is broken down at a faster rate while on the other hand, if the proteases is present in small amount then more time is needed to digest the protein so that's why Claire's small intestine break down the protein at a low rate.

Botany Professor. Dr. Noa Nkembe. is conducting research over how temperature effects the toxicity of Toxicodendron diversilobum (poison oak). He grows the plant in controlled environments that are kept at temperatures that vary by just 0.05 degrees Celsius. Which of the thermometers would be the BEST choice for him to use for this experiment? Justify your answer. A.Glass thermometer B.Temperature probe C.Temperature strip
Answers
Answer:
The correct answer is - option A. Glass thermometer.
Explanation:
Glass or basal thermometers are the instruments that are use to measure temperature of any surface or organism. These are best choice for the measuring smaller changes in the temperature which can vary up to 1/10th of the degree to 1/100th of the degree.
In this case the temperature variation is 0.05 in the environment of the Toxicodendron diversilobum (poison oak) which can easily be monitor with the help of this glass temperature.
Thus, the correct answer is - option A. Glass thermometer.

What forms at a divergent plate boundary such as in the middle of the Atlantic Ocean?
a) Tall mountains
b) Deep valleys
c) Sea mounts
d) Under sea ridge
Answers
Answer:
The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, it separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction respectively. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about 2.5 centimetres (1 in) per year.[1]
